Hanky-panky? Totally decorous on that occasion, I assure you!
Yes, indeed, Air Cdre Brown had lost an eye, and wore an eye-patch over the glass substitute. As the evening wore on, the patch woukd tend to drift up his forehead, obviously unseen by him. I was told he also had a glass eye with an RAF roundel instead of the usual pupil/iris arrangememnt, but never saw that myself.
